Red Meat Allergy: How Tick Bites Can Trigger Life-Threatening Alpha-Gal Syndrome
In 2020, Christine Longette from Asbury Park never imagined that a simple hike would lead to a life-threatening condition. After being covered in Lone Star ticks, she developed alpha-gal syndrome, a severe allergy to sugar found in red meat.
Alpha-gal syndrome typically manifests after tick bites, causing delayed allergic reactions like stomach cramps, vomiting, and hives after consuming pork, beef, lamb, or venison.
Longette, along with many others, has had to drastically alter her lifestyle to avoid triggering the condition.
The syndrome is caused by a sugar molecule, galactose-α-1,3-galactose, which is found in mammal meat.
Dr. Chirag Patel, chief of allergy and immunology at Jersey Shore University Medical Center, explains, “It’s like getting the wrong kind of vaccination. The tick’s saliva triggers the human immune system to form antibodies against the sugar.”
While associated mainly with Lone Star ticks in the U.S., other tick species and chiggers across the world can also transmit the syndrome. Reactions often happen hours after eating meat, as the sugar takes time to release into the bloodstream.
There is no cure, and those with the condition must avoid red meat, dairy, and even certain medications.
As climate change contributes to longer tick seasons, experts like Dr. Catherine Monteleone warn, “It’s becoming more common, and people really need to check for ticks—even in their own backyards.”
Alpha-gal syndrome has already affected hundreds in New Jersey, with more cases expected in the future. For Longette, the condition has changed her life, and her message is clear: be vigilant, as this dangerous allergy could be closer than you think.
